designs with unprecedented scalability and carrier-grade reliability. The ARROW 2488 consists of a SONET/SDH

network interface and framer with integrated SERDES including full section, line, and high-order path processors,

non-blocking memory-based high-order STS/AU and low-order VT/TU cross-connect, low-order VT/TU path

processors, and a large number of expansion interfaces (both ESSI serial links and a Parallel TelecomBus

interface). The SONET/SDH framer, high-order cross-connect, and low-order cross-connect support Message

Assisted Protection Switching (MAPSTM), a mechanism that allows standards-based protection switching without

software intervention.

Optimizes compact multi-port OC-48/STM-16 architectures, while allowing scalability to multi-port OC-

192/STM-64 applications

48/STM-16 mode (one interface operating at 2488.32 Mbit/s)

Quad OC-12/3/STM-4/1 mode (four interfaces operating at 622.08 Mbit/s or 155.52 Mbit/s, selectable per

port)

Single OC-48/STM-16 mode (one interface operating at 2488.32 Mbit/s)

CML compatible serial interfaces to connect to optical transceivers

Framing, high order pointer processing, alarm processing and overhead processing on all received

network streams

Dedicated pins to extract/reinsert B3/N1 path overhead bytes for Tandem Connection Monitoring

Per-framer connection ID message, allowing verication of high order path connectivity across single or

multistage fabrics

mappers

Cross-connect implements HO MAPS algorithm to extract, lter and interpret line status code on a per STS-

1 basis

TOH byte insertion and extraction (99 TOH bytes per port)

Support for a set of active and standby conguration memory pages, permitting new switch settings to be

updated in one page while the TSE operates from the control settings of the other page

2.5 Gbit/s to/from 622 Mbit/s interleaving/de-interleaving

Muxing scheme enables dierent port asset allocations for dierent applications

Congurable, multi-channel, payload processor that aligns and monitors performance of the SONET virtual

tributaries (VTs) or the SDH tributary units (TUs)

Memory-based, LO cross-connect capable of switching at VT/TU granularity

Accepts and switches SONET VT and SDH TU streams. All SONET virtual tributary types (VT1.5, VT2, VT3,

and VT6) All LO SDH tributary unit types (TU11, TU12, TU2, and TU3)

All SONET virtual tributary types (VT1.5, VT2, VT3, and VT6)

All LO SDH tributary unit types (TU11, TU12, TU2, and TU3)

Support for a set of active and standby conguration memory pages, permitting new switch settings to be

updated in one page while the WSE operates from the control settings of the other page

Cross connect implements the Low Order MAPS algorithm to extract, lter, and interpret the line status

code on a per VT/TU basis

ESSI links running at 2.488Gbit/s or 622Mbit/s (selectable per link)

TelecomBus interfaces
